The attacker does this by using a modified lxd-agent that returns inconsistent SFTP directory listings and Lstat results.","state":0,"publishedAt":"2026-09-28T13:22:36.561+00:00","modifiedAt":"2026-09-28T16:32:28.148+00:00","affected":[{"ecosystem":"Vendor product","name":"LXD","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Canonical\",\n                    \"product\": \"LXD\",\n                    \"platforms\": [\n                        \"Linux\"\n                    ],\n                    \"packageName\": \"LXD\",\n                    \"repo\": \"https://github.com/canonical/lxd\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.0.2\",\n                            \"lessThan\": \"4.0.14\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"5.0.0\",\n                            \"lessThan\": \"5.0.10\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"5.21.0\",\n                            \"lessThan\": \"5.21.8\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"6.0\",\n                            \"lessThan\": \"6.9\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:H/A:N","score":5.8,"severity":"MEDIUM"}],"references":["https://github.com/canonical/lxd/security/advisories/GHSA-mr8v-hx34-hfvf"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-87798","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-87798","identifiers":["CVE-2026-87798"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
